His dancing skills made him the first non-human winner of Britain's Got Talent.
Now Pudsey has turned his talents to writing.
'Pudsey: My Autobidography' will be published tomorrow.
The six-year-old mongrel, a Border collie, bichon frise, Chinese crested cross, today turned up with owner Ashleigh Butler at London's Foyles bookshop to promote the book, which is being described as "the story of a small dog's incredible adventure from a puppy growing up in the Butler household to winning one of the nation's favourite television shows".
Ashleigh, 17, is said to have signed a £100,000 deal for the book.
That is on top of the £500,000 prize for winning the sixth Britain's Got Talent contest with that elaborate dance routine performed to the Mission Impossible theme tune.
Pudsey and Ashleigh have also flown to Los Angeles at the behest of Simon Cowell.
The pair, from Wellingborough, Northamptonshire, are embarking on a national tour to promote the book.
